 deciduous, upright-growing shrub, very little known, but 

 verj^ desirable. It was called Ilex Canadensis and Pfinos 

 lucida. The flowers are small and white ; but the berries 

 are large, beautiful crimson, and very ornamental. Com- 

 mon shrubber}^ soil ; but it will do better with an addition

NiCANDRA. [Solan aceas.] Robust half-hardy annual, 

 with blue and white flowers ; pretty, but running too much 

 to foliage. It should be sown in a mild hot-bed with other 

 annuals towards the end of April, and the plants planted 

 out in May ; or it may be sown in the border in May, and 

 all the plants in each patch pulled away but the strongest. 

 When a little stunted, it looks pretty in a large border ; the 

 blossoms then being developed in a greater proportion to 

 the leaves.
